The ups and downs of Halo: Reach multiplayer... how do they affect the human heart? One player decided to monitor his heartbeat during a six minute game session to track the effects of Xbox Live on the old ticker.

Reddit user gortag—who says he's studying for his PhD, even if this project appears to be just for kicks—tracks the highs and lows of his heartbeat, the heart calming effects of death and Armor Lock, the heart stressors of virtual combat. The above image is just a sample of the massive 8259 x 656 image of Halo versus the heart, so head to Reddit for the full picture.
